NHS needs to write to you with a full response within 20 working days of receiving your complaint at the investigation stage. In some cases, the NHS may need more time to give you a full response. If this happens, NHS staff should let you know and tell you why.
If you have not received a response after the time limit, contact the appropriate person at the Health Board or the practice manager to ask why there has been a delay and when you can expect a response. An adviser will be happy to help you with this.
